GLIOMA OR NEURO-EPITHELIOMA OF THE RETINA 173 affected eyes, without any fresh manifestations of the disease. The right eye is affected with the same frequency as the left, and the two sexes equally. Members of the same childship have in rare instances been the subjects of glioma of the retina, but it has not been met with in more than one generation in a k , â â B Fig. 84.âGlioma of the retina A commencing to involve the optic nerve B. The glioma growing from the nuclear layers of the retina C has converted it into a mass of new growth. The portion of the growth A is fungating into the vitreous D. The symptoms at the commencement of the disease vary according to the situation of the growth. If it pro- trudes from the outer surface of the retina it is termed glioma exophytum, if from the inner surface glioma endo- phytum. In the former, which is the more frequent, the retina is displaced inward and seen clinically behind the lens with the opaque white growth beneath it. In the latter the retina remains in position, the tumour extending inward to the vitreous chamber (Fig. 84), detached fiocculent nodules often forming in the vitreous humour. In the rare cases where it starts from the pars ciliaris retinae it grows over the inner surface of the ciliary body, posterior surface of the iris, and anterior surface of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Collins, E.
